Only the 300 kit can be bored in. The 330 kit gets advertised as such at some sites but it leaves the sleeve so thin that cracking develops very quickly resulting a blown top end and usually bottom as well. An HD sleeve is needed for anything larger than the 5MM over piston. Be wary though as many junk pistons are out there.
